Abstract:Monosubstituted 9‐(2‐bromophenyl)‐carbazole (1Br1CZ) and disubstituted 9,9′‐(2,4‐dibromo‐1,3‐phenylene) bis(9H‐carbazole) (2Br2CZ) are synthesized by introducing bromine into ortho‐phenyl position of 9‐phenyl‐carbazole (PhCZ). The decomposition temperature with 5% mass loss and melting point of 2Br2CZ crystal are 360 and 230 °C. The highest occupied molecular orbital energy level of PhCZ is the highest, and that of 2Br2CZ is the lowest. The crystals of PhCZ, 1Br1CZ, and 2Br2CZ are monoclinic, orthorhombic, and… Show more
